## Summary description

The BlueOptics SFPPQSFP28-03-BL is a 3-meter InfiniBand fibre optic cable featuring a QSFP connector on one end and four SFP+ connectors on the other. This cable is designed for high-speed data transfer, making it suitable for data centers and networking applications. Its male-to-male configuration ensures easy connectivity between devices, enhancing network performance and reliability.

## Long description

The BlueOptics SFPPQSFP28-03-BL InfiniBand fibre optic cable is a 3 m interconnect solution with a QSFP connector on one end and four SFP+ connectors on the other. Designed for short-reach, high-speed links in racks and adjacent rack pairs, this male-to-male assembly supports InfiniBand and other high-throughput networking protocols where QSFP-to-4xSFP+ breakout connectivity is required. The 3 metre length is intended for direct attachment between compatible devices in data centres and server rooms.
Advantages
This cable provides a compact QSFP-to-4xSFP+ breakout configuration that simplifies port aggregation and device interconnection. As a 3 m direct attach solution it offers low latency and low power operation for short-distance links. The design follows industry mechanical and electrical form-factor conventions to ensure interoperability with hardware platforms that support QSFP-to-SFP+ breakout connections.
Suitable for
Linking switches and routers within the same rack or adjacent racks
Aggregating four 10 G SFP+ ports to a single 40 G QSFP port
High-throughput InfiniBand connections between compute nodes and storage systems
Short-reach data centre and server-room interconnects
Key specifications
Connector configuration: QSFP on one end, 4 × SFP+ on the other
Cable length: 3 metres
Supported data rates: up to 40 G aggregated via QSFP and up to 10 G per SFP+ lane (protocol-dependent)
Cable type: direct attach (short-reach interconnect for rack environments)
Application support: Ethernet, FCoE, Fibre Channel, InfiniBand (protocol support depends on host hardware)
How to use
Insert the QSFP connector into a compatible 40 G QSFP port and plug the four SFP+ connectors into the respective SFP+ ports on the target device. Ensure that the connected devices support QSFP-to-4xSFP+ breakout mode and the chosen communication protocol. Verify link status and configuration in the device management interface and follow any hardware vendor guidance for passive direct attach cabling.
Usage recommendations
Use this 3 m QSFP-to-4xSFP+ cable for short-distance interconnects inside racks or between adjacent racks. Confirm hardware compatibility and breakout mode support before deployment, avoid excess bending near the connector ends, and route the cable to minimise mechanical stress and airflow obstruction within the rack.
